Early Warning Signs of Parkinson’s Disease

Parkinson’s disease is a progressive neurological condition that affects movement, muscle control, and balance. Symptoms often show up years before anyone gets a formal diagnosis, starting small, a slight hand tremor, a face that’s lost some of its expression, or a voice that’s gone quieter than usual. Catching these signs early changes what’s possible with treatment.

According to Dr. Guruprasad Hosurkar, a neurologist in Bangalore specialising in Parkinson’s disease and movement disorders, “Most patients with Parkinson’s disease have had early motor and non-motor symptoms for two to five years before they ever reach a neurology clinic, and that delay costs them significantly in terms of treatment outcomes.”

Most patients see a general physician first, and the neurological cause gets identified much later.

• Resting tremor: Usually starts in one hand and stays there for months, a low-amplitude shake that only shows up when the hand is idle, and families tend to notice it before the patient does, often dismissing it as stress or tiredness before anyone thinks to investigate further.
• Rigidity: The arms or neck feel stiff in a way that rest doesn’t fix, and it tends to surface in small tasks, not demanding ones, turning over in bed, holding a cup steady, or keeping pace on a walk without the arms swinging naturally.
• Bradykinesia: Writing gets smaller, steps get shorter, and there’s a delay before movement begins that keeps growing, none of which the patient necessarily connects to each other until someone outside points out the overall pattern.
• Postural changes: Slight forward lean while standing, a hesitation before turning, feet that shuffle more than they lift. Individually these seem like nothing, but in combination they signal early postural instability that needs neurological evaluation.

Getting a movement disorders treatment assessment done early is the clearest way to understand what is actually happening.

These symptoms show up before movement is affected at all, which is exactly why they rarely get connected to Parkinson’s at the time.

• REM sleep behaviour disorder: Patients physically act out dreams during sleep, vocalising or moving while still asleep, and while this is now documented as one of the earliest Parkinson’s markers, appearing up to ten years before motor onset, it is almost always attributed to stress at the time it develops.
• Hyposmia: Smell loss unrelated to any respiratory condition, gradual enough that patients adapt to it without flagging it, present in close to 90% of confirmed cases yet rarely connecting to a neurological referral until a diagnosis is already being made on other grounds.
• Gut involvement: Chronic constipation without a dietary or medication-based explanation reflects enteric nervous system changes that now factor directly into disease staging and DBS surgery candidacy decisions.
• Mood changes: Depression or anxiety without an identifiable psychological cause is not incidental in early Parkinson’s, it reflects dopaminergic disruption in mood-regulating circuits and in many patients precedes any motor complaint by several months.

For patients where tremor is the primary concern, Parkinson’s vs Essential Tremor covers the clinical distinctions worth understanding before a first appointment.

Dr. Guruprasad Hosurkar brings 22+ years in neurology and movement disorders to every case, led India’s first Adaptive Closed-Loop DBS programme at KIMS Hospital, and was recognised as Inspiring Neurologist of the Year by the Economic Times in 2021. Patients report that from the first visit, findings are communicated directly and a structured plan is in place, without deferred timelines or generalised advice.
